As always, Jobs was compulsive in preparing for the dramatic unveiling.
Having stopped one rehearsal because he was angry about the CD drive tray,
he stretched out the other rehearsals to make sure the show would be stellar.
He repeatedly went over the climactic moment when he would walk across the stage and proclaim, "Say hello to the new iMac."
He wanted the lighting to be perfect so that the translucence of the new machine would be vivid.
But after a few run-throughs he was still unsatisfied,
an echo of his obsession with stage lighting that Sculley had witnessed at the rehearsals for the original 1984 Macintosh launch.
He ordered the lights to be brighter and come on earlier, but that still didn't please him.
So he jogged down the auditorium aisle and slouched into a center seat, draping his legs over the seat in front.
"Let's keep doing it till we get it right, okay?" he said.
